Graphs
Overview
– Coordinates
– Linear graphs
– Gradient and y = mx + c
– Real-life graphs (To include phone bills and taxi charges)
– Distance-time graphs
Example Key Words
Coordinate
A pair of numbers that describe the position of a point on a graph using the horizontal and vertical distances from the two reference axes.
Linear Graph
A straight line graph
Gradient
The measure of the steepness of a curve.
Y Intercept
The point where the line crosses the y axis
Distance-Time Graph
A graph that plots the distance traveled by an object on a vertical axis against the time taken
